The Cisco® I-Flex approach combines shared port adapters (SPAs) and SPA interface processors (SIPs), providing an extensible design that enables service prioritization for data, voice, and video services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 4-Port and 8-Port 10BASE-T/100BASE-TX Fast Ethernet Shared Port Adapters, Version 2 (Cisco Fast Ethernet SPAs; refer to Figure 1).
Figure 1. Cisco 8-Port 10BASE-T/100BASE-TX Fast Ethernet SPA
The Cisco Fast Ethernet SPAs are available on high-end Cisco routing platforms, offering the benefits of network scalability with lower initial costs and easy upgrades. The Cisco SPA/SIP portfolio continues the company's focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows deployment of different interfaces (packet over SONET/SDH [POS], ATM, Ethernet, etc.) on the same interface processor.
Fast Ethernet interfaces are commonly used to interconnect routers or other devices within a central office or data center or in a metropolitan-area network (MAN). With Cisco Fast Ethernet SPAs, users can mix and match SPA ports with other types of interfaces in the same slot. Each SPA provides standards-based Fast Ethernet implementation for compatibility and interoperability.
The Cisco Fast Ethernet SPAs can be used in any combination of the following applications:
• Residential triple-play services
• Metro Ethernet services
• Converged residential and business services
• Internet peering
• Inter- and intra-point of presence (POP) aggregation
Key Features and Benefits
The Cisco SPA/SIP portfolio offers many advantages, including the following:
– Flexible design allows mixing and matching of interface types on the same interface processor for consistent services, independent of access technology.
– Programmable interface processors provide flexibility for the service diversity required in next-generation networks.
– Innovative design provides intelligent delivery of services without compromising performance.
• Increased speed-to-service revenue
– The programmable Cisco architecture extended to 10 Gbps dramatically improves customer density, increasing potential revenue per platform and facilitating compatibility with future versions.
– Interface breadth (copper, channelized, POS, ATM, and Ethernet) on a modular interface processor allows service providers to quickly roll out new services, facilitating consistent, secure services for all customers, large and small.
– High-density Small Form-Factor Pluggable (SFP) interfaces are featured for high-port-count applications with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.
• Dramatically improved return on your routing purchase
– Improved slot economics and increased density reduce capital expenditures (CapEx).
– The ability to easily add new interfaces as they are needed facilitates a "pay-as-you-grow" business model.
– SPAs are shared across multiple platforms, and can be easily moved from one to another, providing consistent feature support, accelerated product delivery, and significant reduction in operating expenses (OpEx) through common sparing as service needs change.
Table 1 provides specifications of the Cisco Fast Ethernet SPAs, Version 2.
Table 1. Product Specifications
• Cisco Catalyst 6500 Series Switches
• Cisco 7600 Series Router
• Cisco 12000 Series Router (8-port only)
• Cisco XR 12000 Series Router (8-port only)

Port density per SPA
Four or eight Fast Ethernet ports
RJ-45 with support up to 100 meters Category 5 unshielded twisted pair (UTP) or shielded twisted pair (STP) cable
• SPA status - Bicolor green and amber LEDs encode the SPA status as follows:
• LED off: SPA is powered off
• LED amber: SPA is powered on and initializing
• LED green: SPA is powered on and operational
In addition to the status LED, the SPAs also have a bicolor LED dedicated to each port to indicate port status. The green and amber LEDs encode the port status as follows:
• LED off: Port is not activated by software
• LED amber: Port is activated by software, but there is a problem with the Ethernet link
• LED green: Port is activated by software, and there is a valid Ethernet link
Features and functions
• Autonegotiation with autosensing of 10/100 Mbps modes
